Unfortunatelly I can't try preview right now but I will install it as soon as stable version will be released. Meanwhile, is there some workaround?

FWIW, clearing the Visual Studio Test Explorer Extensions cache folder solved this problem for me. Instructions can be found here (scroll down to the red/pink box immediately under the Running tests with Visual Studio section).

At some point, the cache folder stopped existing in my %TEMP% directory. Doing a rm -rf **/bin **/obj in the project directory fixed the issue. I presume it was an stale xunit dependency sticking around.
